Abstract
A cam follower includes a radially inner arcuate bearing surface that matches the curvature of the outer surface of the cam. Engagement of this bearing surface with the surface of the cam opposes undesired motion of the cam follower, including motion radially away from the cam, about an axis perpendicular to the cam rotation axis, and/or about an axis parallel to the cam rotation axis. This arcuate engagement also facilitates effective lubrication of the cam follower. The cam housing is formed with arcuate bearing surfaces that define with the cam surface an annular cam follower cavity and that engage a radially outer arcuate bearing surface of the cam follower, maintaining the cam follower in position against the cam surface.
